普通梁是一种受弯的基本构件,当梁的高度较大,跨度较小,跨度和高度相近时称为深梁。它的受力状态和普通梁(为了区别起见把普通梁称为浅梁)有明显的区别,浅梁和深梁的区别一般使用跨高比作指标(即跨度L和梁高h之比L/h),随着跨高比的由大至小,应力状态是逐渐变化的,但在实用上需要区别的是L/h≤2.0的简支梁和L/h≤2.5的连续梁。因而现在把这种梁称为深梁。对钢筋混凝土深梁的设计计算方法,是由弹性理论为基础过渡到考虑各种极限状态的,1932年美国Frang Dischinger从无穷
Ordinary beams are a kind of basic components subject to bending. They are called deep beams when the beam height is large, the span is small, and the span and height are similar. Its force state and the ordinary beam (for the sake of distinction, the ordinary beam is called the shallow beam) is obviously different. The difference between the shallow beam and the deep beam generally uses the ratio of span to height (ie, the ratio of the span L to the height h of the beam L / h ), With the span from high to low stress state is gradually changing, but in practice need to distinguish between L / h ≤ 2.0 simple beams and L / h ≤ 2.5 continuous beams. So this beam is now called a deep beam. The design and calculation of reinforced deep beams is based on the theory of elasticity transition to consider the various limit states, the United States in 1932 Frang Dischinger from infinity
